Heat-treating process is complicated. It is important to make sure the reason we use them and what the best atmosphere for a specific application is. There are many different types of atmospheres being used, and it is necessary to understand how a particular atmosphere was chosen as well as its advantages and disadvantages and to learn how to control them safely.
Induction hardening is a type of heat treatment that involves the use of induction heating to heat the metal which is then quenched. It requests different types of Induction heating equipment, such as including induction billet heater and Hardening and tempering furnace. During the quenching process, the metal undergoes change that hardens it, increasing the brittleness as well. The induction heating systems are used to harden selected areas of the part or assembly, without affecting the entire part or the properties. Induction heating uses the principle of electromagnetic induction which is a non contact heating process. It produces heat in the inside layer of the work piece.
When a conductive material is placed into a strong magnetic field, electrical current can flow in the steel creating heat. The current that is generated flows mainly in the surface layer. The depth of the layer is determined by surface power density, frequency of alternating field, the material thickness and permeability and the heat time. By quenching the layer in oil, water or other quenching agent, the surface layer changes and becomes much harder.
The induction hardening process is commonly used for surface hardening of steel. An alternating magnetic field is used to heat the components to temperatures that are above or within the transformation range. After the quenching the core of the material remains unchanged by the treatment. The physical properties remain the same as those of the original bar, while the hardness is much higher. The induction heating systems are suitable for use with carbon and alloy steels that have a carbon content that is equal.
High frequency electricity is necessary as a way to drive the huge alternating current through a coil. As current passes through the coil, an intense and fast changing magnetic field is generated. The work piece is placed inside the alternating magnetic field, where the currents that are generated and the resistance causes heating of the metal. This is a process that is very common with steel alloys. Most of the mechanical parts that are readily available, such as gears, shafts and springs are subjected to this treatment to enhance or improve the quality and wear behavior. The hardening process is a vital part of the machine and automotive industry, as well as for other applications that require high resistance to wear.
Design engineers are able to choose from a number of heat treat processes and furnaces for different gear materials and designs. Selection of the appropriate furnace or material is often defined by availability, cost, and application requirements.
